The first internal-combustion engine to operate successfully on the four-stroke cycle used gas as a fuel and was built in 1876 by Nicolaus August Otto, a self-taught German engineer at the Gas-motoreufabrik Deutz factory near Cologne, for many years the largest manufacturer of internal-combustion engines in the world. It was one of Otto’s associates – […]

The main problem in understanding the construction of the reciprocating piston engine is being able to identify and name the various parts making up the power unit. To this end, the following briefly describes the major car engine components and the names given to them : Cylinder block This is a cast structure with cylindrical

Heat is a form of energy that can be sensed by a change in temperature. The engine uses chemical energy in the fuel and converts it into heat and then into movement which how car cooling system works . The energy conversion process in an engine is not very efficient and only about 30% is

From the sump reservoir under the crankshaft oil is drawn through a strainer into the pump which show what is lubrication system or ball, valve that opens when the pressure in the oil exceeds the spring force acting on the valve seat . When the valve opens, a return drilling is uncovered and the excess

The camshaft, on most modern engines, is mounted in bearings formed into the cylinder head via an in-line boring process . The camshaft is forged from steel or cast iron and the bearings and cam surfaces are a smooth, machined finish. The camshaft has cam lobes for each valve and to ensure the correct sequence

This explores various different engine components found on modern road vehicles Engine block and liners Engine cylinders, when cast in a single housing, are known as the engine block. Usually, the engine block is manufactured from cast iron or aluminium alloy. In the latter case, cast iron or steel liners form the cylinder bore. The
